Great wines have always been known to mature over their time. This very character of wine presents itself as a great investment opportunity. Only a finite number of bottles of each particular kind of wine are in existence and as years pass by, the demand is bound to go up - if the particular batch of wine in context is well accepted in the wine circles and is much sought after. Hence with a careful and calculated selection of the make of wine and its professional storage, the price goes up, sooner or later.
